MHB Two Balls Thrown Vertical Upward

Ok. Great. Let us move on. I will post similar word problems in the coming days.

Okay, so we've found:

$$t=\frac{v_0\pm\sqrt{v_0^2-2a\Delta x}}{a}$$

Suppose we have $\Delta x=0$. At what times does that occur?

Replace (delta)x with 0 and simplify, right?

Yes. :)

Thank you for all your help.

Um, okay.

I was attempting to share with you some of the ways I used to go about learning things that helped me succeed in my math studies, but if you just wish to walk away from that, then so be it. Examining formulas at the boundaries of the parameter values gave me a good number of "aha" moments. Looking at how one values changes in relation to another is also illuminating.

I thank you for helping me as I march on my way to succeed with word problems.
